STANDING VALVE.

Application filed April 27, 1925.

This invention relates to traveling barrel pumps, in which there is a standing valve and areciprocatory pump barrel. The novelty of the invention resides in the construction of the standing valve, and particularly in the packing rings and their appurtenances which are so associated that the packing rings are double-acting. There are beveled ends to prevent sand working into the pump barrel past the standing valve, and there are pockets formed for arresting any sand which may by chance work past the rings.

The novelt I of the invention will be clear- 1y understoo by reference to the following description in connection with the accompanying drawings, in which- F'gure- 1 is a view partly in elevation and partly in longitudinal section showing the well tubing, the pumping barrel and the standing valve.

Figure 2 is a vertical longitudinal sectional view through the pump, and

Figure 3 is a disassociated View of two separator rings and a packing ring.

Referring now to the drawings by numerals of reference, 1 designates the well casing or tubing provided at its lower end in the usual way with an anchor collar 2. Within the anchor collar 2 is an anchor check 3 having a tubular connection with the standing valve 4 through a pipe 5. The pump barrel 6 sleeved upon the standing valve, is provided at its upper end with a valve cage 7 surrounding a valve seat (not shown) in which is a ball valve, as will be well understood. At the upper end of the standing valve structure is a seat 8 surrounded by a valve cage 9 in which is a ball valve 10. The construction shown in Figure 2 is illustrative of the valve seat andcheck valve 10 and it is also illustrative of the construction of the valve mechanism in the cage 7. There fore, when the pumping barrel 6 is raised, the ball 10 will lift off its seat to permit oil to pass into the upper chamber 11, and when the barrel moves downward the valve 10 seats, but the corresponding valve in cage 7 will unseat and-permit the oil to pass above the pumpin barrel so that'it can be discharged at t e top of the ground. This general construction is well understood, for example, being illustrated in the Ellis Patent #1,513,699 of October 28, 192 1.

As heretofore pointed out my present in- Serial No. 26,069.

vcntion relates more particularly to the exterior construction of the standing valve. On the bottom end of the tube standard 12 of the standing barrel is a collar 13 pro vided with a ring groove 1 1 to receive an expanding packing ring 15. Alternately. arranged between the collar 13 and the lock nut 16 at the upper end of the standard 12 are packing rings 17 and separators 18. The packing rings are illustrated as comprising cylindrical members 19 sleeved on the hollow standard 12 and having oppositely disposed cone-shaped end portions 20 and 21 with the separator rings 18 interposed between them. The separator rings 18 are eylindrical, being sleeved upon the tubular standard 12, and the opposite ends of the rings 18 are concave as indicated at 22 and 23, the concave portions having surface areas in excess of the ends of the conical portions 20 and 21, it being understood that the conical ends 20 and 21 of the packing rings 19 are in the form of frustrums of cones, and since the separator rings have concave portions larger than the ends of the rings 19, it is obvious that pockets 2 1 will be formed to receive any particles of foreign matter such as sand or the like, which may by chance pass the packing rings. The packing rings are of resilient material such as rubber or the like, the particular material employed, however, may be varied. The

packing rings and the separator rin s may be sleeved upon the hollow standar 12 in alternating relation, and then the lock nut 16 may be screwed down on the threaded portion 25 of the tubular standard 12. The diameters of the packing rings are approximately equal to the inner diameter of the pump barrel, and of course when the lock nut 16 is screwed down as shown in Figure 2, the yielding or resilient packing rings will tend to expand slightly so they will snugly fit within the movable pump barrel.

There is an expanding packing or wiping ring 26 in the groove 27 of the lock nut 16. It corresponds substantially to the ring 15 in the roove 14.

It Wlll be apparent from the foregoing that the packing rings and separators may be conveniently applied, that they will efiiciently packthe working barrel, and that liability of sand and other like foreign ma terial working past the standing valve will be reduced to a minimum, it being apparent that inasmuch as the packing rings have cone-shaped ends, the packing rings become double-acting, that is, due to the friction of the working barrel against the cylindrical portions of the rings, the rings are equally effective through each half of the reciprocatory movement of the working barrel.

What I claim and desire to secure by Letters-Patent is:

1. In combination with the tubular standard of the standing valve of a traveling barrel pump, packing rings on the standard having end portions of less diameter than their body portions and separator rings between the packing rings, the separator rings having recesses in their end faces of greater diameter than the ends of the packing rings and seating the packin rings to retain the packing rings longitu inally and provide annular pockets about the ends of the packing rings for the purpose set forth.

2. The combination, with the tubular standard of the standing valve of a traveling barrel pump, of'packin rings on the tubular standard having cone-s aped ends, and separators between the packing rings, said separators comprising rlngs having concavely curved sockets in the ends thereof, said sockets having diameters greater than the diameters of the ends of the rings to provide sand retaining pockets.

In testimony whereof I aflix my signature.
